where \(x_i^s\)  is the \(i\) -th sample in support set and \(Loc_i\)  is the object region of \(x_i^s\) . We apply a simple WSOL approach [1]} to obtain the location of objects, which is shown in Fig. 4. Firstly, feature maps are extracted from the images in the support set by the feature extractor in metric-based methods, which can be denoted as:
\(p_i = f_\phi (x_i^s),\)
